[0029] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of the cooking machine 100 shown in an exemplary embodiment of the present application. Figure 2 is Figure 1 a cross-sectional view of the cooking machine 100 shown in

[0030] The present application provides a cooking machine 100, and the cooking machine 100 includes, but is not limited to, a wall breaker.

[0031] The cooking machine 100 includes a cup base assembly 10 and a cup assembly 20. The cup assembly 20 is installed above the cup base assembly 10, and the installation method can be an inseparable method.

[0032] The cup base assembly 10 includes an outer shell 11, a motor assembly 12, and a motor cover 13. The outer shell 11 is arranged on the outermost side, which can improve the aesthetics of the cup base assembly 10. The motor assembly 12 is fixedly installed inside the outer shell 11. The motor assembly 12 includes a motor 120 and a wind blade 121, and the wind blade 121 is connected to the rotor 1203 of the motor 120.

[0033] The motor cover 13 is disposed inside the housing 11. The motor cover 13 includes an integrally formed cup holder fixing part 130 and a cover part 131. The cup holder fixing part 130 is connected to the housing 11 and is also used to connect to a cup assembly 20 disposed above the cup holder assembly 10. The cover part 131 is disposed around the outside of the motor 120. The cover part 131 is provided with an air inlet 1310 for air flow to the motor 12 and an air outlet 1311 for air flow to discharge. The fan blade 121 is configured to enable air flow to flow from the air inlet 1310 to the air outlet 1311. The motor assembly 12 can be fixedly installed on the cup holder fixing part 130 or the cover part 131.

[0034] According to the above description, the cup holder fixing part 130 and the cover part 131 are provided as an integrally formed structure, and the cover part 131 does not need to be installed separately, which simplifies the installation process of the cover part 131. Moreover, the cover part 131 is provided with an air inlet 1310 and an air outlet 1311, which can achieve heat dissipation of the motor 120.

[0035] Please refer to Figure 3 , Figure 3 For Figure 2 the enlarged view of some structures in

[0036] In one embodiment, a gap between the cover part 131 and the motor 120 forms an internal air duct 1312, and a gap between the cover part 131 and the housing 11 forms an external air duct 1313. The internal air duct 1312 communicates with the external air duct 1313 via the air inlet 1310 and the air outlet 1311. Thus, the air duct for cooling the motor 120 is located inside the housing 11, and an internal air duct 1312 and an external air duct 1313 that are connected to each other are formed on the inner and outer sides of the cover part 131, achieving heat dissipation of the motor 120. Figure 3 The arrow direction in

[0037] In Figure 3 the embodiment shown, the motor 120 includes a stator core 1201 and a stator winding 1202 fixedly disposed on the stator core 1201. The stator winding 1202 is the main heat-generating component of the motor 120. The air inlet 1310 is disposed at a position corresponding to the stator winding 1202. With such a setting, when air flow enters the internal air duct 1312 from the air inlet 1310, it can directly blow to the stator winding 1202, more effectively cooling the motor 120.

[0038] In one embodiment, the motor 120 further includes a rotor 1203. Along the axial direction of the rotor 1203, the air inlet 1310 is located above the air outlet 1311. The air inlet 1310 being located above can be closer to the stator winding 1202, enabling the air flow to fully contact the stator winding 1202 and enhancing the heat exchange efficiency.

[0039] Please refer to Figures 3 to 4 , Figure 4 which is a schematic diagram of the food processor 100 placed upside down with the housing 11 removed. Figure 5 which is a schematic diagram of the motor cover 13.

[0040] In one embodiment, the impeller 121 is connected to the lowermost end of the rotor 1203 and is located outside the housing portion 131. An opening 1314 is provided at the lower end of the housing portion 131, and the lower end of the rotor 1203 extends out from the opening 1314, so that the impeller 121 is located in the external air duct 1313. Such a setting can prevent the impeller 121 from occupying the internal space of the housing portion 131, making the air outlet smoother and the layout more reasonable.

[0041] In a more specific embodiment, the impeller 121 is disposed in the external air duct 1313 and is higher than the bottom of the external air duct 1313. In this way, ventilation gaps are left on both the upper and lower sides of the impeller 121, making the air outlet smoother.

[0042] In Figure 3 the illustrated embodiment, along the axial direction of the rotor 1203, the height of the air outlet 1311 is higher than the lower end face of the impeller 121. This is more conducive to using the impeller 121 to discharge the air flow from the air outlet 1311 and avoiding the impeller 121 from obstructing the air flow.

[0043] To increase the air flow rate, the impeller 121 can be set as a centrifugal impeller. Moreover, the impeller 121 is arranged to discharge air along the radial direction of the rotor. Radial air discharge can more effectively transport the air flow in the internal air duct 1312 to the external air duct 1313, realizing the rapid circulation of the air flow.

[0044] In one embodiment, to prevent the heat of the motor 120 from accumulating in the housing 11, the housing 11 is set as a heat-absorbing housing. That is to say, the housing 11 can be made of a material with a relatively large thermal conductivity. After the heat in the air flow is transferred to the housing 11, it can also be radiated outward through the housing 11 to achieve heat dissipation.

[0045] In one embodiment, a plurality of air inlets 1310 can be provided, and the plurality of air inlets 1310 are spaced circumferentially on the housing portion 131. The plurality of air inlets 1310 can increase the air intake volume, which is more beneficial to the heat dissipation of the motor 120.

[0046] In one embodiment, as Figure 3 shown, a knife assembly 30 is connected to the top of the rotor 1203, and the knife assembly 30 is disposed in the cup cavity 201 of the cup assembly 20.

[0047] Please continue to refer to Figure 1 , the cup assembly 20 includes a cup body 21 and a cup lid 22, and the cup lid 22 covers the top of the cup body 21. The cup assembly 20 further includes a heating plate 23 and a sealing ring 24 mounted on the bottom of the cup body 21, and the sealing ring 24 is used to seal the gap between the heating plate 23 and the cup body 21. Among them, the cup body 21 is provided with a cup cavity 201, and the heating plate 23 forms the bottom of the cup body 21. The cup seat fixing portion 130 of the motor cover 13 connects the housing 11 and the heating plate 23.

[0048] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
